DETAILED DESCRIPTION OF EMBODIMENTS

Referring to FIGS. 1-7, a preferred storage and mixing container 10comprises a bottle 100 for containing one or more first substances, suchas a liquid 33, a storage repository 17 for containing one or moresecond substances, such as a powder 35. The storage repository 17 isdisposed within an upper opening 110 of the bottle 100 and coupled tothe neck 120 of the bottle 100. This preferred embodiment includes areleasable liner 25 to cover a second upper opening 19 of the storagerepository 17 when the container 10 is used to separately store thepowder 35 from the liquid 33, and a cap 300 including a mixing blade 200that couples to the bottle 100, such as by threads 14.

As depicted in FIGS. 1-3 and FIGS. 5-6, the cap 300 may comprise anelement 200, sometimes referred to as a mixing blade, which is generallycentrally located within the interior of the cap 300. As shown, theelement 200 may be generally ring-shaped and have substantially the samediameter as the lip 18 defining an upper opening to the storagerepository 17. Further, the element 200 may comprise ports 210 throughthe walls thereof. One of ordinary skill in the art will appreciateelement 200 can be implemented in shapes other than circular shapes,such as a square, rectangle, pentagon, and the like; if non-circularshapes are used for element 200, lip 18 should be formed so that itgenerally matches the non-circular shape of and has the same perimeteras element 200.

In various implementations, the element 200 may be formed integrallywithin the cap 300, as shown in FIG. 1, or the element 200 may be formedseparately from the cap 300 and secured within a ring 310 disposed incap 300, as shown in FIG. 1A. In the implementation of FIG. 1A, theelement 200 may be secured within the ring 310 via interference fitand/or otherwise coupled to the cap 300 adhesively, mechanically,magnetically or by other means that will be apparent to one of ordinaryskill in the art.

As depicted in FIGS. 1 and 1A, the container system includes one or morecouplings 400 used so that the storage repository 17 will be disposedwithin an upper opening of the bottle 100 and coupled to the neck 120 ofthe bottle 100. Disposition of the storage repository 17 within thebottle 100 is depicted in FIGS. 6 and 7.

As depicted in FIG. 6, when the cap 300 is coupled to the bottle 100while the releasable liner 25 is present, and the mixing blade 200 iscontacting an upper surface of the releasable liner 25, a seal is formedbetween a lower surface of the releasable liner 25 and the lip 18 of thestorage repository 17. The seal prevents the one or more firstsubstances 33 from mixing with the one or more second substances 35. Asshown in FIG. 6, the cap 300 is coupled to the bottle 100 using threads,but one of ordinary skill in the art will appreciate any number of othermeans can be used to couple cap 300 to bottle 100.

FIG. 7 depicts the container system when the releasable liner 25 hasbeen removed. A gap 37 is provided, comprising space above the one ormore couplings, continuing above the upper opening 110 of the bottle100, and below an interior surface of the top of the cap 300, throughports 210, and into additional open space inside mixing blade 200. Thegap 37 provides additional space to facilitate mixing of liquid 33 andpowder 35. When releasable liner 25 has been removed, liquid 33 may movebetween the bottle 100, gap 37, and storage repository 17 by passingthrough the one or more couplings 400 and ports 210 of the mixing blade200. Likewise, when releasable liner 25 has been removed, powder 35 maymove between the storage repository 17, gap 37, and the bottle 100 bypassing through ports 210 of the mixing blade 200 and the one or morecouplings 400. Such mixing is depicted in FIG. 7, and occurs when, forexample, the bottle 100 is shaken, inverted, or otherwise agitated, oneexample of such agitation being depicted in FIG. 4.

In a preferred embodiment, as depicted in FIGS. 6 and 7, mixing blade200 may have substantially the same height as the height of the spacecreated between the upper opening 110 of the bottle 100 and the interiorsurface of the top of the cap 300, and the diameter of the mixing blademay have substantially the same diameter as the diameter of the lip 18of the storage repository 17. One of ordinary skill in the art willappreciate that mixing blade 200 can be designed with ports 210 havingvirtually any shape, including polygonal shapes such as rectangles,squares, and triangles, or curved shapes, such as circles. Also, thenumber of ports 210 that may be used is not limited to the numberdepicted in FIGS. 1-3.

While the one or more couplings 400 may not be designed so that the oneor more first substances and one or more second substances arecompletely prevented from moving between the bottle 100 and storagerepository 17, one of ordinary skill in the art will appreciate thatvarious couplings may be used to couple the storage repository 17 to theneck 110 of bottle 100. Couplings 400 may consist of a single piece ofmaterial having ports through which the one or more first and secondsubstances may move, or, as depicted in FIGS. 8A and 8B, multiple piecesof material, such as support arms 410, that are placed apart from oneanother to create space through which the one or more first and secondsubstances may move. Also, couplings 400 may be manufactured as onepiece with the storage repository 17 or bottle 100, or may be separatecomponents.

The one or more first substances and the one or more second substancesmay each be in solid form, liquid form, or some combination thereof.Examples of substances that may be used in connection with the containersystem include but are not limited to the following substances: water,dehydrated substances, preservative free substances, dietary supplementmixtures, nutritional mixtures, protein mixtures, dairy based proteins,milk proteins, whey proteins, vegetable based proteins, soy basedproteins, amino-acids, beta alanine, vitamins, minerals, creatine,glutamine, L-arginine, phenylalanine, L-Leucine, L-Isoleucine, L-yaline,synephrine, yohimbe, ginseng, ascorbic acid, hydroxyl citric acid, aloevera, dimethylamyamine, polysaccharide, monosaccharide, maltodextrin,dextrose, fructose, silicon, artificial sweeteners, natural sweeteners,sucralose, artificial or natural flavors, artificial or natural colors,tea, coffee, dairy product, or any other substances which may beconsumed by a user either alone, or in combination with any otherchemical or other substance.

The bottle 100 and storage repository 17 may be constructed of anymaterial suitable for storing liquid or solid substances. In a preferredembodiment, the bottle 100 is manufactured of polyethylene terephthalate(PET). One of ordinary skill in the art will appreciate that othermaterials also could be used to manufacture said bottle 100 or storagerepository 17, such as other plastics (including High DensityPolyethylene and polypropylene), glass, metal, styrofoam and the like.It is contemplated that alternate embodiments of the container systemmay be constructed of materials suitable for heating within a microwaveoven or other heating apparatus. Cap 300, mixing blade 200, and the oneor more couplings 400 may likewise be constructed of any suitablematerials, including those identified above.

The purpose of releasable liner 25 is to prevent the mixing of the oneor more first substances and the one or more second substances. One ofordinary skill in the art will therefore appreciate releasable liner 25can be implemented in the container system of the present disclosure inmany different ways. Releasable liner 25 may cover first upper opening110 of the bottle 100 and the second upper opening 19 of storagerepository 17, but one of ordinary skill in the art will appreciatereleasable liner 25 need only cover second upper opening 19. Releasableliner 25 may be a gasket, i.e., it may be loosely placed over secondupper opening 19 in the absence of cap 300 being placed on bottle 100,so that the releasable liner 25 might fall off when cap 300 is removed.Or, releasable liner 25 might be coupled to bottle 100 and/or lip 18using an adhesive. Releasable liner 25 could even be formed in the shapeof a sphere, such as a marble, or a spherical cone, and be disposed insecond upper opening 19 of storage repository 17.

It is believed the operation and construction of the apparatus andmethod disclosed herein will be apparent from the foregoing description.While the apparatus and method shown and described has beencharacterized as being preferred, it will be readily apparent thatvarious changes and modifications could be made without departing fromthe spirit and scope of the disclosure.
